PicassoIA Image Editor Pro

1. 1

   Create the prediction

   Send the input in a POST. The API answers 201 at once, without waiting for the result: the prediction is in the starting state, with an estimate in eta and the address to poll in urls.get.

2. 2

   Poll it until it finishes

   Ask urls.get again after eta.next_poll_in_seconds: at half the estimate, when the estimate is reached, then every 2 seconds. Polling faster gets you nothing sooner.

   Request

   # Repeat after eta.next_poll_in_seconds until status is
   # succeeded, failed or canceled.

   Read the result

   When status is succeeded, output is a list of image URLs. Download the files you want to keep.

   If status is failed, error says why; canceled means it was canceled before it finished. These three statuses are final: the prediction never changes again.

   Request

   # The last poll holds the result: "output" when "status" is succeeded,
   # "error" when it is failed. With jq, just those three fields:
